Virtual Scanner is an open-source MR platform for end-to-end simulation and serves as a digital twin for real MR scanners in hardware and software aspects. In this update, we present new functions including RF pulse design and simulation, hardware-incorporated Bloch simulation that takes into account B0 and B1- fields, and non-Cartesian reconstruction. Three Google Colab notebooks are provided to demonstrate these functions and enable users to perform virtual experiments in a zero-footprint manner. Furthermore, we demonstrate the digital twin concept in a development iteration case using the SPGR sequence.
